Lower Calorific Value (= Net Calorific Value - NCV = Lower Heating Value - LHV) - the products of combustion contains the water vapor and the heat in the water vapor is not recovered; The table below gives the gross and net heating value of fossil fuels as well as some alternative biobased fuels.
10 Μαρ 2022 · As an alternative to diesel, the power sector can afford gas for predominantly peaking capacity at delivered prices of up to R300/GJ, whilst the transport sector’s affordability threshold for gas is R100–300/GJ. These affordability thresholds are the highest because of the high price of diesel.
Hongsheng Guo. Brian Liko. William Stuart Neill. As an inexpensive and low carbon fuel, the combustion of natural gas reduces fuel cost and generates less carbon dioxide emissions...
16 Φεβ 2022 · The Role of Gas in South Africa’s Path to Net-Zero analyses how gas can enable the integration of renewable energy at scale in the power sector and the phase-out of coal as a feedstock in the production of synthetic fuels (synfuels).
1 Οκτ 2014 · Comparing natural gas and diesel engine emissions, it was found that natural gas fueled SI engine emissions of total hydrocarbon (THC), nitrogen oxides (NO x), and particulate matter (PM) were significantly lower than that of the diesel fueled engine.
15 Ιουλ 2024 · As the brief highlights, natural gas emits 50% to 60% less CO2 than coal. This makes it an ideal transition fuel for South Africa that will contribute only a very miniscule amount to global emissions. And even that could be decreased with the use of carbon capture and storage.
1 Σεπ 2022 · The IRP 2019 indicates that the cost of unserved power is estimated to be ZAR 49 per kWh , so at the low usage factors expected from dispatchable power, natural gas, liquefied petroleum gas (LPG) or diesel generation can provide this power at cost below this value, while coal and nuclear generation cannot.
